Embodiment Construction

[0041] According to a first embodiment of the present invention, there is provided a light module device, hereinafter referred to as "CLM" (Compact Light Module). The principle structure of CLM and the schematic diagram of light modulation are in figure 1 described in. The CLM 100 includes a light source 10 emitting light of a first color C1; a pixelated optical element 20 arranged to receive light emitted from the light source 10; and an addressable pixelated optical shutter 30, hereinafter referred to as An optical shutter, from which the light modulated by the optical shutter 30 is output from the CLM 100, is disposed in front of the pixelated optical element 20.

[0042] The pixelated optical element 20 , hereinafter referred to as optical element, comprises sub-areas with color-converting functions and non-converting sub-areas. Specifically, the optical element 20 has: a non-converting pixel 21 through which light from the light source 10 passes; The light color is con...

Abstract

This invention relates to illumination systems for projection type display systems, and more particularly to a light module device comprising a light source, which emits light of a first color, and a pixelated optical element, which is arranged to receive the emitted light. The pixelated optical element comprises a first set of pixels for color converting a fraction of the emitted light of the first color into a second color, a second set of pixels for color converting a fraction of the emitted light of the first color to a third color, and a third set of pixels which are non-converting for passing a fraction of the emitted light. The device further comprises an addressable pixelated optical shutter arranged in front of the pixelated optical element for modulating light received from the pixelated optical element and as a result outputs light from said device, which output light comprises light of three colors which are modulated by the addressable pixelated optical shutter.

Description

technical field [0001] The present invention generally relates to lighting systems for projection-type display systems, and more particularly to light module devices. Background technique [0002] The use of light emitting diodes (LEDs) is well known in lighting applications, such as projectors for displaying images on a projection screen or similar surface for viewing by a user. Usually, in current LED projectors, based on liquid crystal display (LCD) and digital light processing (DLP) projection systems respectively, two or three LED modules with three primary colors of red, green, and blue are utilized and replaced previously used UHP lamps and color filters or color wheels used in projector systems. DLP projection systems are a class of LED projectors that have become popular in recent years. In these systems the image is produced by illuminating a digital micromirror device (DMD), which is a matrix of microscopically small controllable mirrors on a semiconductor chip,...
